中文摘要:对北京地区微灌常用的6种文丘里施肥器进行了试验,在理论分析的基础上结合相关数据,建立了6种文丘里施肥器吸肥量、入口流量、临界流量和临界压差的回归模型并进行了比较分析。结果表明:进、出口压力直接影响了施肥器的吸肥量和入口流量,施肥器YR、RF对压力波动等不利工况较敏感,而AD系列和NF则更能适应波动的工作压力环境。NF和AD-1等临界压差小,工作区间大;而RF和YR工作区间小,只有临界压差达到进口压力1/2以后才可正常吸肥。文丘里施肥器的结构对其水力性能影响较大。

Abstract:An experiment on six Venturi injectors in Beijing was carried out. Based on theory studies, the differences of fertilization performance including fertilizer suction amount, the inlet discharge, the critical discharge and the critical pressure were analyzed and the regression models were built. It showed that the fertilizer suction amount and the inlet discharge were affected by the inlet and the outlet pressure directly. Domestic brands YR and RF were sensitive to the pressure fluctuation, while foreign models NF and AD could adjust to work environment better. The critical pressure of brands NF and AD-1 were very low, thus these models have a long working range. In contrast, the critical pressure of the models RF and YR got to a half of the inlet pressure for a normal fertilization, and this means they have a short working range. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
